INSTRUCTIONS

1

Turn on the Sauté setting on the Instant Pot. Sauté 2 oz onion, 1 tbsp garlic, and 2 oz carrots in 1 tbsp olive oil and 1/2 tbsp unsalted butter for 2 minutes. Stir occasionally until the onion starts to turn translucent.

2

Add 8 oz mushroom. Sauté for 3 minutes.

3

Add 6 oz tuna, 4 oz green peas, 1/2 tsp salt, 1/2 tsp thyme, 1/2 tsp ground black pepper, 1/4 tsp paprika, 2 tsp Dijon mustard, and 1 tsp lemon juice. Stir.

4

Add 6 oz tagliatelle pasta, 1/4 cup whole milk, and 1 1/2 cup unsalted chicken broth. Stir.

5

Close the lid and set the steam release valve to the sealing position. Cook on the “Meat/Stew” setting for 10 minutes.

6

When the timer is up, open the lid, and turn the steam release valve to the venting position to perform a quick-release of the steam. Stir 4 tbsp heavy cream and 2 oz cheddar cheese into the Instant Pot.

7

Take the pot out. Divide the tuna casserole into serving portions and sprinkle 2 tbsp freshly chopped parsley on top. Serve hot with a side dish of choice.
